Cassandra Warren was in a rush and feeling a little overwhelmed with work and planning her wedding. As she was getting invitation for her wedding in the mail one day, she addressed one to her aunt and uncle in Eugene, Oregon, about 20 minutes from where she lived.

A week later, the invitation came back. She had mistakenly written down the wrong address. A handwritten note was written on the return envelope: “I wish I knew you —this is going to be a blast. Congratulations — go and have dinner on me. I’ve been married for 40 years—it gets better with age.” A $20 bill was put inside.

Cassandra was at a bit of a professional crossroads and had been having a tough day. In fact, she’d been complaining to her fiance, Jesse Jone, about her frustrations just as she opened the misdirected envelope. Then she read the note.

“It was kind of prefect timing,” said Cassandra, who worked as a nanny. “I was really grateful for it.”

And the magic envelope wasn’t finished with its surprises. Cassandra looked closer and saw that the person had written “Live long and prosper” on the envelop, a nod to Star Trek (《星际迷航》).

“We’re kind of Star Trek fans,” she said.

Cassandra, 26, and Jesse, 24, had no idea who the mystery note writer was. But they figured the Star Trek reference was because the person noticed the corner of their invitation, which had both a Star War sword and a Harry Potter wand (魔杖).

“She assumed we’d understand her message,” Cassandra said, “Which we did.”

Cassandra, who was a counselor (顾问) for families with autistic children, went out to dinner the following night with a friend who was going overseas with military. They happily put the $20 toward their bill.

Then Cassandra stopped by a store and bought another card — a thank-you card. She wrote her aunt and uncle’s incorrect address on the envelope again -- this time on purpose —and addressed it to “Kind Stranger”.

Inside, she wrote, “Thank you for the note and taking the time to send it. Not many people would have done that. It was a big blessing after the day I was having. I am thankful for people like you still being in the world.” Don’t miss other real-life acts of kindness like this one that will warm your heart.

Zachariah Fike has an unusual hobby. He finds old military (军队的) medals for sale in antique stores and on the Internet. But unlike most collectors, Zac tracks down the medals’ rightful owners, and returns them.

His effort to reunite families with lost medals began with a Christmas gift from his mother, a Purple Heart with the name Corrado A. G. Piccoli, found in an antique shop. Zac knows the meaning of a Purple Heart—he earned one himself in a war as a soldier. So when his mother gave him the medal, he knew right away what he had to do.

Through the Internet, Zac tracked down Corrado’s sister Adeline Rockko. But when he finally reached her, the woman flooded him with questions: “Who are you? What antique shop?” However, when she hung up, she regretted the way she had handled the call. So she called Zac back and apologized. Soon she drove to meet Zac in Watertown, N.Y. “At that point, I knew she meant business,” Zac says. “To drive eight hours to come to see me.”

The Piccolis grew up the children of Italian immigrants in Watertown. Corrado, a translator for the Army during WWII, was killed in action in Europe.

Before hearing from Zac, Adeline hadn’t realized the medal was missing. Like many military medals, the one Zac’s mother had found was a family treasure. “This medal was very precious to my parents. Only on special occasions (场合) would they take it out and let us hold it in our hands,” Adeline says.

As a child, Adeline couldn’t understand why the medal was so significant. “But as I grew older,” Adeline says, “and missed my brother more and more, I realized that was the only thing we had left.” Corrado Piccoli’s Purple Heart medal now hangs at the Italian American Civic Association in Watertown.

Zac recently returned another lost medal to a family in Alabama. Since he first reunited Corrado’s medal, Zac says his record is now 5 for 5.

At age12, Jane was diagnosed with a rare and deadly cancer, and was informed that high-risk surgery was her only chance of getting better. Jane received the surgery, and things got extremely hard during the two-year treatment that followed – she couldn’t even remember how many times she was rushed to the ICU. However, she never gave up hope and, thankfully, she survived. Shortly after recovery, she decided to help find out the cause of this disease. In doing so, she took an internship at a medical lab, despite being quite busy with her schoolwork, and invited people to donate tissue samples for research purposed everywhere she went. She is determined to live a fulfilling life regardless of what the future holds, and to try her best to help patients with this cancer recover in spite of the various difficulties she might face.
